A digraph is semicomplete if it has no pair of non-adjacent vertices. A tournament is a semicomplete digraph with no directed 2-cycles. Tournaments form the most well studied class of directed graphs and a lot is known about their structure, ranging...

The Pacific Institute for the Mathematical Sciences (PIMS) was founded in 1996, and Simon Fraser University is a founding member. The members of PIMS now include all the major Canadian research universities west of Ontario, as well as universities in...

The response of the muscle-tissue unit (MTU) to activation and applied forces is affected by the architectural details as well as the material properties of this nearly-incompressible tissue. We will describe the (highly nonlinear) elastic equations...

"Cops and Robbers" is a well-known pursuit game played on a graph. There are two players, one controls the cops and the other controls the robber, who take turns moving along edges of the graph. The goal of the cops is to capture the robber, which is...

Wachs and White introduced four statistics on restricted growth functions or RGFs. An RGF is a sequence of positive integers $w=w_1w_2\dots w_n$ such that $w_1=1$ and $w_i \leq 1+\maw_1w_2\dots w_{i-1})$. We say that an RGF $w$ avoids $v$ if there is...

This talk is intended for those who, like the speaker, have at some point wondered whether there is a theory of three- or higher-dimensional matrices that parallels matrix theory. A d-dimensional hypermatrix may be viewed as a coordinate...

I will present a general approach for constructing a Markov process that describes the dynamics of a process when one or more observables of this process are observed to fluctuate in time away from their typical values. This will extend some well...

For linear transport equation with diffusive scaling, classical diffusion may fail when the diffusion matrix becomes unbounded, which can be attributed to two reasons. One comes from the heavy tail equilibrium and the other is due to the degenerate...
